>>36237128Masuda was both director and a producer of BW, along with 3 other producers. The exec producers are Tajiri, Iwata, and Ishihara.
Unno was director of BW2, but the exec producers are the same, and they only lost one normal producer.
Masuda is back as director for XY, they got a new fourth producer, and the execs are the same.
Ohmori directs ORAS, same producers and exec producers.
Ohmori again for SM, another of the four producers was replaced, and now we have Kimishima in place as head of Nintendo.
Iwao directs USUM, and Masuda got booted from being producer for another person. There is now a General Producer (whatever that is) called Shinya Takahashi.
Looking to see what Masuda did in USUM, I found a second set of producers that included Masuda and Ohmori. As far as I know, this second set doesn't exist in the other credits, but I didn't look hard.
Details on the producers:
the one added for XY was Takato Utsunomiya, and the one added for Sun/Moon was Shin Uwai. Masuda himself got replaced by someone called Takanori Sowa.
